Who's who in the Russia investigation?

Numerous people are now somehow connected to the investigation into Russian interference in the 2016 election and connections between Trump associates and the Russian government. They range from Congressmen to White House aides to Russian diplomats and Justice Department officials.

Here are 21 people currently involved in the investigation into the Russia matter -- including President Donald Trump -- and how they all fit into the big picture.

Jared Kushner

Kushner, 36, is the husband of Ivanka Trump

In 2008, he became CEO of Kushner Companies, a real estate business founded by his father, after the elder Kushner was sentenced to prison for tax evasion and other charges by then-U.S. Attorney Chris Christie

Along with campaign adviser Michael Flynn, Kushner met with Russian Envoy Sergey Kislyak on Dec. 2, 2016, during the presidential transition. He discussed setting up a "back channel" to Kremlin, a story first reported by the Washington Post and confirmed by CBS News

The conversations between Kushner and Kislyak were intercepted by American intelligence

Kushner urged Mr. Trump to fire FBI Director James Comey

On Tuesday, Mr. Trump retweeted a Fox News story that cited an unnamed source in saying that Kushner and Kislyak's conversation "focused on Syria"

Met with Russian banker Sergey Gorkov, another meeting that has attracted scrutiny. The New York Times reports that investigators want to know more about his motives for meeting with Gorkov, who heads the sanctioned Russian bank VEB and is close to Vladimir Putin

Despite his family ties to Mr. Trump, there is a growing sense in the White House that Kushner is now "vulnerable" due to a recent spate of negative stories about him

Michael Flynn

Was paid over $30,000 for attending and speaking at event organized by Russian media outlet RT, and received tens of thousands of dollars from entities with Russian ties during the 2016 campaign when he acted as a Trump surrogate

Flynn resigned from his White House position after 'misleading' Vice President Pence and not disclosing discussions with Russia

Flynn invoked the Fifth Amendment's protection against self-incrimination and did not initially comply with a Senate subpoena seeking documents on Russian interference

Citing three current and former U.S officials, The New York Times reported that Manafort used to lobby for deposed Ukrainian President Viktor Yanukovich's political party

CBS News confirmed that a secret, handwritten ledger earmarking billions of dollars in undisclosed cash that were allegedly given out by Yanukovych's party exists. Manafort's name appeared in the ledger 12 times, for a sum of $12.7 million between 2007 and 2012.

Manafort resigned from the Trump campaign after mounting pressure and scrutiny over his ties to pro-Russian politicians in Ukraine

Manafort then took steps to register as a foreign agent with the federal government

Manafort sent documents to the Senate Intelligence Committee related to the Russian meddling investigations, and sources familiar with Manafort's thinking say he will volunteer to be interviewed

Former Trump campaign foreign policy adviser

Page visited Moscow in July 2016 for a speech at the New Economic School where he criticized the U.S.

Page spoke with Russian ambassador Sergey Kislyak at an event on the sidelines of the Republican National Convention along with then-Senator Jeff Sessions

The Washington Post reported that FBI officials obtained a secret court order during the campaign to monitor Page's communications because the government had reason to believe Page was acting as a Russian agent, including contacts Page had with Russian intelligence operatives in 2013

Page informed Congressional committee members that he is willing to testify before lawmakers about his knowledge of any Russian interference, but only in the form of an open hearing

Sergey Kislyak

Became Russian Ambassador to the U.S. in 2008, and before that, worked as ambassador to NATO from 1998 to 2003 and deputy foreign minister from 2003 to 2008

Kislyak met privately with President Trump and Secretary of State Rex Tillerson, along with Tillerson's counterpart, Russia Foreign Minister Sergey Lavrov, at the White House on May 11, and only Russian state-run media was permitted when Mr. Trump reportedly shared classified intelligence

Sergey Gorkov

Sergei Karpukhin

Considered one of Putin's associates, but he has not played a distinct diplomatic role in the past

Currently, he heads Russian development bank Vnesheconombank (VEB), which was sanctioned by the Obama administration after Russia's annexation of Crimea in 2014, and formerly he worked for Russian businesses such as Menatep Bank, Yukos Oil Company, and Sberbank of Russia

Gorkov studied law at the Academy of the Federal Security Service (FSB), a Russian spy agency, in the early '90s and studied finance in the early 2000's at Plekhanov Russian Academy of Economics

He reportedly met Jared Kushner in December 2016 after Sergey Kislyak requested the engagement, and according to White House spokesperson Hope Hicks, it lasted around 30 minutes and ended with Gorkov requesting continued open dialogue

Fired Acting U.S. Attorney General Sally Yates, who warned the White House that Michael Flynn could be compromised by Russia and was lying to the Vice President; U.S. attorney for the Southern District of New York Preet Bharara, who was leading its own investigations into possible ties to Russia and alleged wiretapping of Trump Tower; FBI Director James Comey, who led a probe into any communications between the Trump team and Russian officials

Mueller had been serving as a partner at law firm WilmerHale, which reportedly represents Ivanka Trump, Jared Kushner and Paul Manafort

Mueller stood with Comey, the deputy attorney general in 2004, after he threatened to resign when the White House overruled the Justice Department finding that wiretapping without a court order was unconstitutional

Mueller advised graduates at his granddaughter's college preparatory school Monday, "Whatever we do, we must act with honesty and with integrity. And regardless of your chosen career, you are only as good as your word. You can be smart, aggressive, articulate and be persuasive, but if you are not honest, your reputation will suffer and once lost, a good reputation can never be regained"

James Comey

Mr. Trump has said that he fired Comey after Deputy Attorney General Rod Rosenstein recommended his removal, but he has contradicted that claim multiple times. Just a few days after the dismissal, Mr. Trump told NBC News that he thought of the "made up" story about ties between Russia and himself when he fired Comey. And in an Oval Office meeting with top Russian officials, Mr. Trump called Comey a "real nut job" whose firing relieved "great pressure" on him

Serves as chairman of the Senate Intelligence Committee, a position he took in January 2015

Burr has invited James Comey to testify about his dismissal as FBI director several times. He and his Democratic counterpart, Mark Warner, said that Comey has agreed to testify after the Memorial Day recess, though a date hasn't been set yet

Burr and Warner have been praised for working closely together on a bipartisan basis in their panel's investigation of Russian interference in the election

Despite his recusal, Sessions played a role in the firing of James Comey as FBI director, who was charged with investigating possible collusion between the Trump campaign and Russia. Sessions wrote in a letter to Mr. Trump the day Comey was fired, "I have concluded that a fresh start is needed at the leadership of the FBI"

In April, Nunes recused himself from his committee's Russia investigation after reports of secret meetings between the California representative and White House officials surfaced and prompted an investigation by the House Ethics Committee into his own behavior

In these meetings, it is reported that the Trump administration officials provided intelligence reports containing highly classified information to Nunes

The House Ethics Committee, a separate organization from the House Intelligence Committee, released a statement that they were investigating the "public allegations that Representative Devin Nunes may have made unauthorized disclosures of classified information"

Republican chairman of the House Oversight and Government Reform Committee who recently announced he will not be running for reelection in 2018 and is resigning from office next month

At first, was hesitant to become involved in matters related to any ties between Russia and Trump associates and Comey's firing, but in recent weeks has become more active in those matters

Requested memos Comey reportedly wrote describing how Mr. Trump asked him to end the Russia investigation -- but the FBI rejected that request

Has invited Comey to testify before the oversight panel

Elijah Cummings

As the ranking Democratic member on the House Oversight and Government Reform Committee, Cummings pushed for tougher oversight of Mr. Trump and any ties between Russia and Trump associates earlier than Chaffetz did

Has said the White House is "stonewalling" the FBI's investigation into Trump associates' alleged ties to Russia and has called for an independent commission -- arguably stronger than a special counsel -- to investigate any ties between Mr. Trump or his associates and Russia

Has called the Russia probe a "fight for the soul of our democracy"
